So I can understand how it's immersion-shattering for you, I really can. To be honest, seeing a wasteland filled with supermodels would make me want to gouge my eyes out. They look more like what you'd expect to find in a post-apocalyptic wasteland. The vanilla bodies are more 'average', they look like they've had wear and tear, they look like they're used to hard work more than exercise. In the real world, not every lady you'll meet has a perfect hourglass figure, and not every bloke you'll encounter will be a body builder (with an incredibly hairy chest, in some instances), and perfectly toned. The vanilla bodies look more like real world people.

I'd love a body that sticks to the vanilla type, to the be honest, but does it in a more detailed away. Being salvaged by little green men in flying saucers, using tractor beams. I mean, I have poor sight, but I don't need models to have hippos where hips should be in order to perceive femininity, they tend to have all the tact and subtlety of a train wreck. This is true of every body mod for the ladies of the Fallout Universe that I've ever seen. Thinking about this, I find Type 3 bodies requiring more suspension of disbelief than the magical underwear.
